Spaceflight wreaks havoc on liver metabolism
Researchers have demonstrated that microgravity and other environmental factors in space play different roles in inducing oxidative stress, which, in turn, alters the metabolism of sulfur-containing compounds in the liver of mice. The study highlight.....»»
Does spaceflight increase men"s risk of erectile dysfunction?
During missions into space, astronauts are exposed to high levels of galactic cosmic radiation and weightlessness. Simulation experiments in male rats indicated that these aspects of spaceflight can negatively affect vascular tissues relevant to erec.....»»

Wild animals that survive limb loss are astonishing. And a sign of the havoc humans are wreaking on nature
It might seem astounding that a wild animal could survive a limb amputation and still thrive in the wild but videos from social media and research show this may be more common than people realize. Many wild animals not only survive the health risks o.....»»
Unlocking pathways to break down problem proteins presents new treatment opportunities
When targeting problem proteins involved in causing or spreading disease, a drug will often clog up a protein's active site so it can't function and wreak havoc. New strategies for dealing with these proteins can send these proteins to different type.....»»

The UK Space Agency and a US spaceflight services company have signed an initial agreement as they bid to send British astronauts into orbit for two weeks, the agency said Wednesday......»»
How eggs of the Zika-carrying mosquito survive desiccation
Eggs of the mosquito that carries Zika virus can tolerate extended desiccation by altering their metabolism, according to a new study published October 24th in the open access journal PLOS Biology by Anjana Prasad, Sunil Laxman, and colleagues at the.....»»
Storm Babet caused dangerous floods as the "dry side" of Scotland isn"t used to such torrential rain
Storm Babet has caused havoc across the UK, with strong winds and rough seas along the east coast, record breaking rainfall and river levels in Scotland, overtopped flood defenses, closed roads and railways and sadly at least two deaths. The impacts.....»»
Study results indicate organophosphorus flame retardants induce malformations in avian embryos
Tris(2-chloroisopropyl) phosphate (TCIPP) is one of the organophosphorus flame retardants that has been detected in the environment, and in the eggs, feathers, and liver of birds. Early developmental avian embryos are known to be sensitive to chemica.....»»
